The 2004 Ford F-150 does not have instrument cluster problems, though it can obviously still go bad. If it stops working then You likely have a bad ground or a bad fuse. To get to the fuse box look to the left of the steering wheel look for a small seam or crack along the dash. Using a screwdriver or prybar You will want to pop this open. On the inside, You will find a bunch of fuses. On the back of the panel that You pulled open, You will see a diagram that will show You what each of the fuses is for. If this is not on the back of the panel then You can also find it in the owner's annual for the vehicle. Once You have figured out which fuse You need simply pull it out. The two sections that stick up should be connected by a thin strip of metal. If this has been broken then the fuse is no good and will need to be replaced. If this strip is there then the fuse is fine and can be popped back in. New fuses will cost You about 10 dollars, so they are pretty cheap.

Main plug at top left corner does not make good contact with the brake light pin. Sometimes can be moved and brake light will go out bad connector or soldier joint on back of cluster repair. Or take to shop
